STM32H743 Nucleo board SEGGER JLink issue

Hi There,

I bought two STM32H743 Nucleo boards recently and did some tests on them. As usual, I first converted ST-Link v2 to JLink interface using the tool SEGGER provided. I have done this with F1, F4, and F7 series boards in order to use JLink RTT for debugging and never had any issue in the past. But when I tried with the new H743 board, I am not able to download the program to the chip using the JLinkExe command line, the way which I usually download programs to STM boards. Even though I can download to the H743 board using the AC3 IDE provided by STM, I am not able to debug after that. Right after the program is downloaded, it run in a wired loop and never be able to stop. Also I am not able to see the RTT debug outputs using the JLinkRTTClient terminal, as usual. I googled a couple of times regarding this question but got no answer.

Can you please kindly give me some hints for how to deal this kind of problems? Any comment will be highly appreciated!

Best regards,

Xiaoguang

The solution is simple, define all RAM regions: 0x20000000 0x1F400,0x24000000 0x7D000,0x30000000 0x46500,0x38000000 0xFA00,0x00000000 0xFA00 in RTT_Viewer0693W000007D4w8QAC.png
